A political committee consists of nine Democrats and eight Republicans. A subcommittee of nine people needs to be formed from this group. (For this problem, define a success as a Democrat being selected for the subcommittee.) a. Determine the probability that this subcommittee will consist of five Democrats and four Republicans if they were randomly selected. b. Calculate the mean and standard deviation of this distribution

Answers

Answer 1

The possibility or chance of an event happening is measured by probability. It is often stated as a number between 0 and 1, where 0 denotes an impossible event and 1 denotes a certain event.

a. To determine the probability that the subcommittee will consist of 5 Democrats and 4 Republicans, we can use the combination formula. The total number of ways to form a subcommittee of 9 people from 17 is C(17,9). The number of ways to select 5 Democrats from 9 is C(9,5) and the number of ways to select 4 Republicans from 8 is C(8,4). The probability is calculated as follows:

P(5 Democrats, 4 Republicans) = [C(9,5) * C(8,4)] / C(17,9)

b. The mean and standard deviation of this distribution can be calculated using the binomial distribution formula, where n = 9 (subcommittee size), and p = 9/17 (probability of selecting a Democrat).

Mean (μ) = n * p = 9 * (9/17) ≈ 4.76
Variance (σ^2) = n * p * (1-p) = 9 * (9/17) * (8/17) ≈ 2.25
Standard Deviation (σ) = √(σ^2) = √(2.25) ≈ 1.50

So, the mean is approximately 4.76 and the standard deviation is approximately 1.50.

Why can we relate/make connections between the Breaking Point of water tension on a penny with the condition of the United States during this time period

Answers

Answer:

We relate/make connections between the Breaking Point of water tension on a penny with the condition of the United States during this time period is explained below in detail.

Explanation:

This is because conventional tap water has greater surface pressure, so the surface is “more powerful” and can hold collectively a bigger drop. Adding detergent reduces the water's surface pressure so the drop becomes smaller and splits apart quickly. As drops of water are combined onto a penny, the sticking force between the water and the penny holds the water from dropping off.

How powerful a thank you can be

Plss help at least
500-600 words
ASAP

Answers

Answer:

The two most powerful words you can say in life aren’t what you’d expect.

It’s not “love you” or “I’m sorry”—though those are quite commanding as well. It’s not “me too”—although that is affirming and potent in its own right.

The most impactful thing you can ever say is “thank you.” Yes, really.

Saying “thank you” is a compelling way to wipe the slate clean. Saying “thank you” is a 2-for-1 gift of gratitude and forgiveness all wrapped in one. Saying “thank you” is the turning point between letting go of what’s happened and embracing what’s to come.

Perhaps the biggest reason why saying thanks is extremely powerful is that it is an acknowledgement that you have grown. Even if you might not have enjoyed the process of getting to where you are, it is a hat tip to the role it played in helping to shape you into who you’ve become. “Thank you” says, “I’m happy just the way I am and exactly with how things turned out.” “Thank you” is a form of vulnerability that drives out and defeats shame.Thank you,” then, is a form of self-love—a wave of compassion sent back inward that recognizes the strength it took to overcome the hardships and challenges to get to where you are today. Brick by brick you’ve built a more formidable foundation from which you can appreciate your past and embrace the future. And that House of Strength was built with little bricks of appreciation that say, “thank you.”Being thankful—and truly meaning it—is a shift in energy that attracts new and exciting things into your life because it signals that you’re ready to receive them. Gratitude opens up little doors in your heart that you previously kept locked. And when those doors unlock and open, it’s possible for you to pick and choose your own adventure. It’s possible to start over. It’s possible to pursue any direction your heart can imagine.

“Thank you” is the key to unlocking your true potential. All you have to do is recognize that you’ve had the power within you all alongWhether it’s to the kind cashier at the grocery store, your nightmare former boss or an ex whom you truly loved—”thank you” shows that you recognize the value of a situation or a person in your life. It is a tremendous display of respect because it shows you appreciate that person’s presence. Thus, the expression of “thank you” in this context is ultimately a realization of the oneness of all things. You dignifying another person in this way is also a way to dignify yourself—to become conscious that we are all one in the same.

It’s also an incredibly empowering nod to something bigger, bolder and grander than you could ever imagine. Because it shows that you understand there are forces at play that are beyond your control but that you find beautiful nonetheless.

Most Latino men believe the man should be the provider for the family. The strength of this belief decreases ______.

Answers

The correct answer to this open question is the following.

Although there are no options for this question or further context or references, we can say the following.

Most Latino men believe the man should be the provider for the family. The strength of this belief decreases in modern-day society because many women work and have similar or better salaries than men.

For years, and as part of the Hispanic culture and belief systems, it is the man who has to provide for the family while women stay in the house raising children.

But under the present circumstances, both parents have to work to get a better income to support the family. And in some cases, women earn more money than man, affecting the pride of Latino men that were raised in this old-fashion way of thinking.

D. Spain

Explanation:

It was in 1540 that Spanish explorer Hernando de Soto first made contact with the Choctaws and the Chickasaws. Soto and his company of conquistadors were sent on an expedition, and he was the very first European to see the Mississippi river. He was buried in the river, as a matter of fact, after dying from a fever. Throughout his life as an explorer, Soto traveled to several places in the American continent, helping conquer lands. No wonder he did not receive any blessings from the natives upon his death.

In one or two paragraphs, explain how Islam led to the beginning of the Muslim Empire. What role did Islam play for the rulers of the Muslim Empire?

Answers

Answer:

Islam played an important role in starting the Muslim Empire. Before the birth of Islam, the people on the Arabian Peninsula were divided and lived different lifestyles. Once they became followers of Islam, they were united by the religion and followed Muhammad as their leader. Muhammad served as both the leader of the Muslim Empire and the leader of Islam.

After Muhammad's death, the Muslim Empire was ruled by caliphs, who were both religious and political leaders. Different families controlled the Muslim Empire, but Islam was very important. The Umayyad caliphate lost power when Muslims throughout the empire were unhappy that their leaders were not following religious rules.

Explanation:

Islam was crucial in establishing the Muslim Empire. The inhabitants of the Arabian Peninsula were split and led various lifestyles prior to the advent of Islam. Once they embraced Islam, they were bound together by the faith and took Muhammad as their leader. Muhammad was the founder of Islam and the ruler of the Muslim Empire.

Following Muhammad's demise, caliphs—religious and political leaders—ruled the Muslim Empire. Islam played a significant role in the Muslim Empire, which was ruled by many families. Muslims throughout the empire revolted against the  caliphate because their officials did not uphold religious tenets, which led to their downfall.

Who was Prophet Muhamad(saw)?

Muhammad, the founder of Islam, was a prominent religious, social, and political figure in the Arab world. He was a prophet who preached and validated the monotheistic teachings of Adam, Abraham, Moses, Jesus, and other prophets, in accordance with Islamic doctrine.

Within Islam, he is revered as the Prophets' Seal. The Quran, together with Muhammad's teachings and actions, served as the cornerstone of Islamic religious belief and helped to unite Arabia into a single Muslim government. Muhammad was born in Mecca around 570 CE. He was the child of Amina bint Wahb and Abdullah ibn Abd al-Muttalib. A few months before Muhammad was born, his father Abdullah, the son of Quraysh tribe leader Abd al-Muttalib ibn Hashim, passed away. He was six when his mother Amina passed away.
